Why will only this appear but nothing else?
Fluid Cache End is set only to 50 and for second Domain 500 even animation ends in 1000
Source - Particle System is set, but you didnt specify which one (second field bellow)

Additional issue can come from ...

you set cache directory same for both domains
(it means second will overwrite first one bake)
each flow affects all domains, if you expect one flow affects one domain and another flow affects second domain you have to set them into collections and set specific collection to each domain

Also I see you use Blender 2.82.7, would be more effective to use actual official release 2.83.1 to avoid possible bugs.
